Shadow vs TSG

I am currently in a SP/ Resto Sham/ Fury team and we are hitting a brick wall against TSG. The DK and war just tunnel me and despite peels i just can't get enough distance to build any pressure and am constantly in defensive mode. We have had limited success at the start on the warrior but he shield walls. Psychic horror can disarm i know but when you are trying to burst I really don't want to be wasting orbs on it.
